PATENT ARCHIE ANDERSON, OF SAN JOSE, CALIFORNIA, ASSIGNOR OF TWO-THIRDS TO FRANK A. WERT AND EDMOND P.v BODEN, OF SAME PLACE.

MACHINE FOR EXTERMINATING GROUND-BURROWING ANIMALS.

SPECIFICATION forming part of Letters Patent No. 329,252, dated October 27, 1885.

Application filed August 12, 1885. Serial No. 174,218. (No model.)

To all whom it may concern.-

Be it known that I, ARCHIE ANDERSON, of San J os, California, have invented a Machine for Exterminating Ground-Burrowing Animals, of which the following is a specification. 1

The object of my inventionis to provide a means for exterminating ground burrowing animals, such as gophers, moles, and squirrels. I accomplish this object by the means illustrated in the accompanying drawings, in which- Figure l is a side elevation of my animalexterminator; and Fig. 2 is a vertical section, in elevation, of the same.

In carrying out my inventionl construct of thin sheet metal a tube or pipe, A, of any desired size and length to receive the bellows or mechanism for operating the same, to the lower end of which I connect, by rivets or otherwise, a funnel-shaped tube, B, the lower end of the main pipe A fitting into the upper end of the funnel B, as shown, while a fuel or combustion chamber, B, is formed in the pipe above, to which access is had by means of a covered feed-pipe, B An annular rabbet is made in the main pipe at O which receives and holds a perforated plate or diaphragm, O, to be hereinafter more fully described. Above the perforated plate in the main pipe is made a ledge, D, upon which rests the lower end of the bellows which I employ, and prevents it from working downward, while between the perforated plate and the ledge D and the lower end of the bellows is formed an air-chamber, E. The pipe is divided at E, and has a lip, E, which shuts down over the inner edge of the divided pipe for convenience in removing the bellows.

My bellows I construct of leather or other.

flexible material and of a diameter sufficient to fit the bore of the body or main pipe. It is provided with two end disks, F and G, which carry the valves F and G. Both of the valves open downwardly, and the lower face of the lower valve is lined with asbestus to render it fire-proof. The bellows is supported internally by the hoops H, and a handle, I, for operating the bellows is connected to the upper head or disk, as shown, and a side or steadying handle is attached to the outer surface of the pipe or cylinder at J.

In practice some light material that will produce by combustion as great a volume of smoke as possible is placed in the combustion-chamber B, through the medium of the feed-pipe B and fired,when the tapering end of the machine is placed in the hole of the burrowing animal, and the bellows operated up and down in the body of the pipe, which receives atmospheric air through its upper valve and forces it out through the lower valve into the chamber beneath and onward through the perforated diaphragm or plate into the combustion-chamber, carrying with it the smoke from the combustion-chamber and forcing it through the tapering tube or funnel into the hole of the animal,which soon causes suffocation and death. It should here be observed that if the ground be porous, or outward channels be found communicating with the holes operated upon, these should be closed with earth, so that the smoke will not escape and its effect be lost or lessened. By this means it will be seen that I provide a portable machine that can be easily carried from place to place or hole to hole and quickly operated.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In an animal or insect exterminator, the

combination and arrangement in one ma-.

chine of a fire-proof portable cylinder provided with a tapering end and a combustionchamber and air-chamber, together with an internally-operatin g bellows, constructed substantially'in the manner asherein set forth and specified.

2. In a ground-burrowing-animal exterminator, the main cylinder provided with a tapering end tube and a combustion-chamber with feed-pipe, an air-chamber separated from the combustion-chamber by a perforated plate, together with a suitable space in the cylinder above for operating a bellows, constructed, arranged, and operating substantially in the manner as set forth and specified.

In testimony that I claim the foregoing I have hereunto set my hand and seal.

ARCHIE ANDERSON. [L. s]-
